Berg, Oakland, Calif., assignor to Kaiser Aluminum & Chemical Corporation, Oakland, Calif., a corporation of Delaware Continuation of application Ser. No. 412,079, Nov. 18, 1964. This application June 8, 1967, Ser. No. 644,738 2 Claims. (Cl. 52-520) ABSTRACT OF THE DISCLOSURE An elongated one-piece clip formed from sheet metal or the like for use in fastening interlocked panel sections to an underlying roofing structure and the like. The body of the clip is generally made in the form of an inverted channel-shaped structure provided with flanged sidewall portions and a series of openings in the web portion, whereby one of the openings of the clip is always in alignment with a support element of the underlying structure in order that the clip can be positively fastened thereto. One end of the clip includes a hooked portion for disposition between and interengagement with the interengaging flanged edges of a pair of interlocked panel sections. The inverted channel-shape of the clip along with the hooked portion thereof when engaged with a pair of panel elements prevents twisting and distortion of the clip.

This application is a continuation of application Ser. No. 412,079 filed Nov. 18, 1964 and now abandoned which is a continuation in part of application Ser. No. 326,134 filed Nov. 26, 1963 and now abandoned in favor of the continuation application Ser. No. 540,106 filed April 14, 1966 now Patent No. 3,312,031.

The present invention relates to roof structures and the like and more particularly to an improved one-piece clip means that can be advantageously used in combination with interlocking panel sections during the application of a roof covering to a building structure.

Accordingly, it is a primary purpose of the instant invention to provide an improved one-piece clip means for a roof structure and the like wherein the novel clip means is interconnected in a unique fashion to interlocking panel sections to provide an eflicient initial roof covering for a roof structure or a reroof covering for a weathered conventional roof structure. This clip means is particularly useful in applying to a roof structure the panel elements disclosed in my copending application Ser. No. 326,134 filed Nov. 26, 1963, and now abandoned in favor of continuation application Ser. No. 540,106 filed April 14, 1966, now Patent No. 3,312,031, of which this application is a continuation-in-part.

This and other purposes of the instant invention will become more apparent from review of the following detailed description when taken in conjunction with the appended drawings, wherein:

FIGURE 1 is a perspective view of a preferred embodiment of the novel clip of the instant invention;

FIGURE 2 is a plan view on a reduced scale of an arrangement for recovering a conventional roof structure and embodying the clip means of the instant invention wherein certain parts are broken away and other parts are shown in dotted lines for the purposes of clarity;

FIGURE 3 is a sectional view generally taken along line 33 of FIG. 1 and with parts removed; and

FIGURE 4 is a fragmented perspective view of the underside of the clip shown in FIGURE 1.

With further reference to the drawing, and in particular to FIGURES l and 4, a preferred form of clip means that can be used in carrying out the teachings of the instant invention generally comprises a novel onepiece clip 10. In one advantageous embodiment of the invention the clip 10 is used with panel sections 12 in providing a recovering for a conventional roof structure 14, encompassing wood shingles 16 and underlying sheath boards 18. The individual wood shingles 16 are secured in an appropriate fashion to the underlying sheath boards 18 and these boards are fastened in a generally parallel pattern to the conventional supporting rafter boards 20. In providing the roof covering a sheet 17 of moisture resistant material, such as asphalt, can be beneficially disposed between the shingles 16 and the sheath boards 18 as shown in FIG. 2. It is to be observed here that although the covering construction incorporating the novel clip 10 of the instant invention will be described with particular reference to a recovering for a conventional roof structure it can be employed equally as well during covering or recovering of other structures such as siding structures and the like.

Referring to FIGURE 1, the one-piece clip 10 of unique shape is fabricated from a blank of sheet material preferably of aluminum or a suitable aluminum alloy. The clip is formed into shape by a suitable die forming apparatus in such a fashion that it is generally symmetrical along its longitudinal axis and approximates a channel shape wherein the main upstanding wall portions 24 and 26 thereof are interconnected by a web portion 28. The wall portions 24 and 26 are advantageously provided with flanges or terminal portions 30 and 32 which are bent outwardly to extend in opposite lateral directions away from the wall portions 24 and 26. These terminal portions 30 and 32 are also spaced from but are arranged generally parallel to the web 28 for a substantial portion of the length of the clip. The web portion 28 desirably includes a plurality of holes generally indicated at 34. These holes are preferably equally spaced from each other with their centers generally coinciding with the longitudinal axis of the clip 10. It is to be understood that any number of holes can be provided and arranged in any pattern in order to meet the requirements for a particular application of the clip 20 of the instant invention.

One longitudinal end of the clip 10 is provided with a hook means. For the purpose of providing such hook means, the terminal portions at the one longitudinal end of the flanges 30 and 32 are inclined upwardly, in the manner indicated at 36 and 38, whereby the wall portions 24 and 26 are progressively reduced in lateral extent or taper toward this particular longitudinal end of the clip 10. The inclined terminal portions 36 and 38 of the flanges at this longitudinal end of the clip are provided with identical ear projections 40 and 42. These ear projections 40 and 42 are folded back underneath the respective inclined terminal portions 36 and 38 to define the hook means 44 shown in FIGURES 2 and 4.

Although the web portion 28 can extend in a generally parallel fashion to the flanges 30 and 32, the preferred embodiment of the invention contemplates that the web portion 28 actually has a slight downward incline relative to the flange portions 30 and 32 for a substantial portion of the length of the clip. If desired, the web portion 28 may be slightly beveled, beginning approximately at point or line 28a, to further increase this slight downward inclination of the web portion. One reason for the web portion 28 being slightly inclined relative to the terminal portions 30 ad 32 adjacent the top of the clip is that each clip 10 of the instant invention is geometrically proportioned to underlie the respective panel sections 12 associated therewith but without disturbing the esthetic appearance of the interlocking panel sections 12. By virtue of the initial fiat shape of a blank coupled with its being formed by suitable die apparatus as aforementioned into the clip 10 of the instant invention, the free side edges 46 and 48 of the terminal portions 30 and 32 converge intermediate the length of the clip 10 to define apices 50 and 52 which are located adjacent the upwardly inclined portions 36 and 38.

The panel sections 12 are desirably formed from a blank of sheet material, preferably aluminum or aluminum alloy, to simulate a series of different-size shingles on their exposed surface as shown in FIG. 2. These panel sections can be made in the form of the panel section shown and described in my co-pending patent application Ser. No. 326,134 filed Nov. 26, 1963, and now abandoned in favor of continuation application Ser. No. 540,106 filed April 4, 1966, now Patent No. 3,312,031, or they can have other configurations. Regardless of the particular type of panel section 12 which is employed the opposed edges of such a panel section will always be provided with upper and lower folded-back flanges 54 and 56 as well as side flanges 58 and 60. The upper flanged edge 60 at the right-hand end of each panel section 12 as viewed in FIG. 2 is provided with a nail hole 62 adjacent the end of the flange 54. The purpose of the hole 62 in each panel section 12 is to enable initial fastening of a panel section 12 by means of a suitable nail fastener to one of the shingles 16 or a similar element to be covered.

Three interlocking panel sections 12 are shown in FIG. 2 wherein the lower flanged edge 56 of the upper panel section 12 is interlocked to the aligned upper flanged edges 54 of two lower interconnected panel sections 12. These panel sections 12 are representative of the manner of installation of the clip 10 with the panel sections 12 as well as the interlocking of the panel sections 12. Prior to interlocking the lower flanged edge 56 of the upper panel section 12 to the upper flanged edges 54 of the lower interconnected panel sections 12, the cars 40 and 42 that define the hook of the clip 10 are brought into engagement with the upper flanged edge 54 of the left panel section 12 in the lower row in FIG. 2. After this engagement of the hooked clip 10 the downwardly facing surfaces 30a and 32a of the terminal portions 30 and 32 are brought into nesting contact with the exposed surface of an underlying roof shingle 16 and secured to the roof structure 14 in a unique fashion by virtue of the holes 34. These holes allow the roofer to line up the clip fastener means with the underlying structure made up of sheath boards 18 or the like and roofing nails are driven through these openings. The roofer drives a nail fastener through any one of the holes until the resistance of the nail fastener being driven indicates that the nail fastener has been successfully driven into a sheath board 18. As indicated in FIG. 2, the conventional nail fastener 22 is driven into the sheath board 18 at the hole 34 that is closed to the hook means 44 of the clip 10, while at the same time being aligned with a solid object or sheath board 18. Although it is evident upon an inspection of FIG. 2 that the other holes 34 could have guided the nail fastener 22 into the sheath board 18, at least one nail fastener 22 is always driven into the hole 34 that is aligned with the sheath board 18 and at the same time closest to the hooked longitudinal end of the clip 10. When the clip 10 is properly emplaced it will have the greatest strength or resistance to bending whenever the distance between the book 44 of the clip 10 and one of the nail fasteners 22 driven through one of the holes 34 is at a minimum. Once the clip 10 is fastened to the underlying sheath board 18 the lower flanged edge 56 of the panel section 12 in an upper row is interlocked to the upper flanged edges 54 of the two panel sections 12 in a lower row. Thereafter, the upper panel section 12 is initially located in an interlocked and offset position with respect to the two lower panel sections 12 by driving a suitable nail fastener (not shown) through the nail holes 62 on the flanged edge 60 and into an underlying wood shingle 16 of the roof structure 14. Additional upper and lower panel sections 12 can be secured in place in a similar fashion to complete the reroofing structure. In the event that the local weather conditions or building codes require that more than one clip 10 be used under a given panel section 12 a plurality of the same may be used.

Whereas in roofing constructions of the prior art no truly suitable roofing clip means has been developed, the clip means of the instant invention has proved eminently satisfactory for initial roofing or reroofing purposes. One of the reasons for the failure of previously developed clips was due to the fact that these clips were not specificall designed to be fastened to a sheath board in a special fashion. Prior art clips were fastened to the supporting roof structure in only a haphazard fashion and for the most part were merely affixed to the weathered shingles which are a relatively poor anchoring medium.

By virtue of the structure of the one-piece clip 10 of the instant invention and the fact that it can be anchored to a sheath board the clip not only has great resistance to longitudinal flexure but it is also positively held by the sheath board 18 to which it is fastened.

An advantageous embodiment of the invention has been shown and described. It will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope thereof as set forth in the appended claims; wherein:

What is claimed is:

1. In a covering for a building structure provided with underlying sheath boards the combination of a plurality of panel sections each of which is provided with interengaging top and bottom flanged edges for interlocking the individual panel sections together, an elongated clip disposed in interlocked relationship with a pair of adjacent panel sections at a point of interengagement between the top and bottom flanged edges of said sections, said clip being of approximate inverted channel shape whereby it is provided with spaced flanges and upstanding portions interconnected by a web-portion, said webportion having a plurality of holes projecting therethrough and spaced from the longitudinal ends of the clip whereby when the clip is emplaced at least one of said holes will always be in alignment with an underlying sheath board, the terminal portions of said flanges adjacent one end of said clip being inclined upwardly out of the normal planes of the remaining portions thereof but while remaining full connected to and integrated with said web portion and said terminal portions being further provided with ears which are folded back to form hook means for engaging in an interlocked relationship the opposing top and bottom flanged edges of the said pair of adjacent panel sections when a fastener means is passed through the one of said holes in the clip and acts to secure the clip and associated panel sections to an underlying sheath board.
